Leaky Car Battery is a dripping car battery. He has battery acid leaking out from his top and has a jagged, toothy smile, which is also bubbling with acid. His eyes are spiraled and crossed, as if he is suffering from an electric shock.
- Leaky Car Battery is one of two battery-based Grosseries from Series 2, the other being Flat Battery.
- His static art gives him a missing tooth, which his figure lacks. He does appear to have a gap printed for a missing tooth in his catalog art, however.
